Hubert Chang - third Google co-founder?

In the video Change recalls how he was introduced to Page and Brin by Stanford computer science professor Rajeev Motwani in January 1997 and how the three of them began to work together on the search engine that would grow to become an Internet search giant in the modern world. Today, Google Inc. has a market capitalization of $138 billion and Page and Brin are worth $16 billion each, according to Forbes.

"Google was designed by Larry, Sergey and me, in February 1997," Chang said in in his video. "The design includes the search engine algorithm, the business model (also called AdSense and AdWords), the name of the company, the outline of the system architecture, a corporation culture like a grad school, and Google's growing path."

Chang said, later, in September 1997, when Page and Brin asked him if he would like to put his name on the academic paper that first described Google's Web page ranking system, he declined, choosing instead to focus on his Ph.D. dissertation at NYU.

"It may seem unwise now, but it made sense then," Chang said, as he had to finish his Ph.D. and "putting names on the paper is the commitment to finish the Google project."

"It was an uncomfortable and difficult decision," he said.

After completing his Ph.D., Chang said he tried to contact Page and Brin but did not hear much from them.
